We look at the division of 392558 by 89 
We want to divide 392558 by 89.

Step 1:
The number 89 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 89

Going ahead to step 2:
39 divided by 89 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 89

Step 3:
When dividing 392 by 89, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 36 after subtracting 356 from 392.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 89

On to step 4:
If we divide 365 by 89, we get 4 and a remainder of 9.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 356 from 365 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 89

Going ahead to step 5:
If we divide 95 by 89, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 441.0
If we take 89 away from 95, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 89

Advancing to step 6:
The number 89 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 4410.0
The remainder is 68 after subtracting 0 from 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
680 divided by 89 is 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 4410.7
If we take 623 away from 680, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 8:
89 can be fit into 570 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 4410.76
Subtract 534 from 570 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
89 can be fit into 360 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4410.764
If we take 356 away from 360, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 89, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4410.764
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
If we divide 400 by 89, we get 4 and a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 4410.76404
The remainder is 44 after subtracting 356 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
89 goes into 440 4 times with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 4410.764044
Subtract 356 from 440 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 4410.764044, with a leftover of 8.4e-06.
